soldering iron advice.

It has become apparent in my that a soldering iron is my next necessary resource/skill. Wondering what I am looking for in a good one, or any tips on what other people use. The use will be arduino circuit building. thanks

I like an adjustable iron. Sometimes you have some heaver piece you need to solder, such as a switch hold down onto a pcb and it takes more heat for that. Plus it has hot air gun that can be used soldering/unsoldering for surface mounted components and heat shrink tubing. I don't know if this kind i am showing in my picture is available in your area, but i only paid $67 USD for it new.
